.To @ZZ Zyl/hom, it may concern:

lowing is a specification.

My invention relates to improvements in a machine for removing the fiber from jute, ramie, and other fibrous plants in which liuted or grooved rollers work in combination with a set of smooth rollers and with beaters; and the objects of my invention are':rst,-to remove the fiber from jute, ramie, or other fibrous plants without injuring the fiber, as also to do the work in an expeditious manner; second, to provide a means by which the fiber can be combed and freed of all small particles of the woody portion of the plant. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a side elevation of my machine,

and Fig. 2 a plan vienrl of same.`

Similar letters refer to similar parts throughout the several views.

To a suitable frame, F, is bolted a housing, H. This housing H carries and supports the journals of shafts of the smooth receiving and feeding rollers R B, the luted or grooved crushing-rollers G G,a nd the roughing-beaters B B, placed in position one behind the other in the order named,'as shown on the plan.

Motion is transmittedto the smooth receiving and feeding rollers B B and to the uted or grooved `crushing-rollers G G by the pinion p, placed on shaft s, and working into the pinion d, placed on shaft a of the lower smooth roller B, and pinion c, placed on shaft f of the lower luted or grooved crushing-roller G, as shown, the upper smooth receiving and feeding roller R being driven by the crown-wheels XV, and the upper luted or grooved crushingroller G being driven by the crown-wheels V, as shown. v A

Motion is imparted to the shafts by the pinion t, placed on shaft h, working into spur-msecured to shaft s, as shown, the shaft h being driven from countershaft by bell b,working on the pulley L, secured to shaft h, as shown. The top roughing-beater is driven by the belt g,

' working on the pulley n, placed on shaft M, and

on the pulley K,placed on the shaft z ofthe top beater,asshown. Thebottom roughing-beater, B, is driven by the crown-wheels J.

' Motion is imparted to the shaft M by the belt Q, working on pulley Y, secured to shaft h, and on the pulley X, placed on shaft M, as shown. The nishing-beaterl? is secured to a shaft, O, which shaft works in journal-boxes secured to uprights of frame F, as shown. Motion is imparted to this shaft O by a belt fromvcountershaft workingon pulley T, secured to shaft O, as shown. l

YThe smooth receiving and feeding rollers R are turned perfectly smooth and true, and are made to make about fifty revolutions per minute. These rollers receive the stalks and feed same to the uted or grooved crushing-rollers G evenly. The tension or resistance of these rollers R can be regulated by the spring z' and set-screwo. The tinted or grooved crushingrollers G are iiuted, as shown, so that the woody portion of the stalk passing through same is brok-en in short pieces. The teeth of these luted rollers are about three-fourths of an inch deep, and the bottom and top of teeth are rounded off,and the rollers are so set that the 'tooth ofone of the rollers f works into the groove of the other roller. The rollers G are also provided with a spring, e, and setscrew o', as shown, to ad mit of the regulating of same to any pressure desired. These rollers G are driven at about fifty revolutions per minute.

The roughing-beaters B consist of four iron blades, u, secured to a suitable drum, these,

blades u being placed on edge, and extend the whole length of drum, as shown. These roughing-beaters B receive the stalk after same has been broken in pieces inpassing through the iiuted or grooved crushing-rollers G, and knocks out the larger portion of the broken woody substance of the stalk. These beaters B are driven at about one hundred and twentyflve revolutions perminute.

The short finishing-beater P consists of four iron blades, Z, placed on edge, and secured to a suitable drum, similar to the roughing-beaters B. The finishing-beater l? is provided wit-h a sheet-metalico'vering, C, to protect the operator. A spray of water' from the pipe E is allowed to play on this finishing-beater P, to keep the fiber from adhering to it. The ob- Aject of this finishing beater P is to comb IOO out any small pieces of woody matter which may not have been ydislodged in passing through the roughing-beaters B. This nishing-beater Pis made to make about four hundred revolutions per minute. As the stalks pass through the smooth receiving and feedinn` rollers Rand the uted or grooved rollers G they receive a spray of water from the pipes N N, which pipes extend the length of rollers, and are perforated with small holes.

D is a tank, placed between the frames F, and under the machina-to collect all the dbris falling from the machine.

Having thus described the construction of myimproved machinery for removing the ber from jute, rarnie, or other brous plants, the operation of same is as follows: The stalk or plants are fed to the receiving and feeding rollers R, which areset to squeeze them sufficiently to spread the stalks and feed same evenly to the grooved or fluted rollers G, which are set so that the woody portion of the stalk is broken in small pieces without cutting or breaking the fiber of stalk. Thewater which is allowed to ow on the rollers R and G from pipe N keeps the ber from adhering to the rollers. After the stalks are broken in passing through the uted or grooved rollers G they pass between the roughing-beaters B, which knocks out the greater portion of the lwoody substance of stalks, and the dbris falls into the tank D. As the ber leaves the roughingbeaters B it is grasped by the operator, who takes the ber and holds it onto the nishingbeater P, where all the small particles of woody matter which were not taken out by the roughingbeaters B are combed out, leaving the ber freed of all the woody portions of stalk and ready for tlie chemical bath, in which the outer cuticle and all vegetable and gummy matter are removed. After the bath the ber is thoronghly rinsed in clean running Water,lwhen it is rea-dy for the loom.

I am aware that heretofore machines have rollers, and revolving beaters a supplementalfinishing-beater cylinder arranged adjacent to lthe main revolving beaters, so that after the fibrous plants have been passed through the machine proper the ber product may be fed by hand to the supplemental beaters to thoroughly clear it of woody matter.

Having thus described the construction and operation of my machine for removing the ber from jute, ramie, and other fibrous plants, I claim as new and desire to secure by Letters Patentl. The combination, with smooth feed-rollers, grooved crushing-rollcrs, and revolving beaters, of a supplemental nishingLcylinder provided with radial beaters, said supplemental cylinder being arranged with relation to the main rollers substantially as described, so that the material being treated may be fed by hand to said. supplemental beaters after passing through the main rollers, sxibstantially as de scribed.

2. The combination, with a series of feedrollers, crushing-rollers, and main beaters, of asupplemental beater, to whose action the fiber is subjected after being grasped by the hand of the operator from the main beaters, substantially as described. e

3. The combination, with the tank D and housing H, of the feed-rollers, crushing-rollers, and main beaters, all arranged, as described, above said tank, and provided with spray-pipes and an independent revolving nishing-beater, against which the ber is held by hand after it passes from the main beaters, and a spraypipe, E, substantially as described.
